STM32H503: How to check I3C in Target mode to become Active Controller is successful

[supriya1]

Hi ,

I have developed a testcase where STM32H503 i3c is in target mode, requesting for controller role request that is going to controller (checked interrupt - Secondary Controller received Controller Role Request ) . After controller is sending GETACCCR command to target but in target side I3C_EVR.CCRUPDF bit is not set. Can you please guide me how to check CRR request.

Hello @supriya1 ,

You can check this example: \STM32Cube_FW_H5_V1.6.0\Projects\NUCLEO-H563ZI\Examples\I3C\I3C_Target_Switch_To_Controller.
STM32CubeH5/Projects/NUCLEO-H563ZI/Examples/I3C at main · STMicroelectronics/STM32CubeH5 · GitHub

It can help you with the CRR request.
